IMPROVEMENT IN MIDDLINGS-SEPARATORS.

Specication forming part of Letters Patent No. 211,683, dated January28, 1879; application filed October 30, 1878.

To all whom 'it may concern Be it known that I, WILLIAM P. ANTHONY, ofChambersburg, in the county of Franklin and State of Pennsylvania, haveinvented a `new and useful Improvement in Middlings off the dust` andother light impurities, and

separating the middlings into different grades.

A represents the frame of the machine, which is provided at its sideswith a perma nent and at its ends with a detachable casing. B is theshoe, to the lower part of the forward end of which are attached thelower ends of two elastic :metal straps, C. The upper ends of the strapsor hangers G are attached to the upper forward part of the frame A.

'.lo the upper part of the rear end of the shoe B are attached the lowerends of two elastic metal straps or hangers, D, the upper ends of whichare attached to the upper rear part ot' the frame A. The straps orhangers O D thus support the shoe B, and at the same time y allow it tobe vibrated longitudinally.

The meal or middlings are fed into the machine from one or more spoutsupon an inclined feed-board, E, attached to the upper part ofthe forwardend of the shoe B.

To the Vupper side of the lower part of the upper feed-board, E, isattached a strip or cleat, e', the lower edge of which is cut away orhas long notches formed in it, through which the middlin gs must pass inescaping from the said feed-board E, so as to be evenly distributed.

From the lower edge of the feed-board E the middlings fall upon theintermediate or reversed feed-board, F, which is inclined in theopposite direction from the feed-board E,

and from the lower edge of which the middlings fall upon the feed-boardG. The feedboard Gr inclines in the same direction as the feed-board E,and from its lower edge the middlings pass to theV screen H.

To the lower edge of the intermediate board, F, or of two or of all ofthe feed-boards, is attached a narrow upwardly-projecting strip or rib,f', over which the middlings must pass, and by which the said middlingsare more evenly distributed, so that they will pass to the screen H in athin sheet. The same effect may be produced in substantially the saineway by forming a groove in the upper side of the lower part of the saiddistributing board or boards.

The screen H rests upon cleats attached to the sides of the shoe B,where it is locked in place by buttons hl, pivoted to the sides of thesaid shoe B. The screen H may be made in two parts, if desired, withtheir adjacent ends overlapping each other, so that the middlings mayreadily pass from the upper to the lower part.

The part of the middlings which passes through the screen H falls uponthe inclined chute or guide-board I, and slides down it to the spout J,through which it passes out into some suitable receiver. The chute I isplaced in grooves formed by attaching cleats to the sides of the shoe B.

Any middlings that may pass through the forward or upper part ofthescreen H fall upon the inclined board K, and slide down it to the spoutJ.

The part of the middlin gs which cannot pass through the screen H fallsfrom the lower end of the said screen to the upper end of the screen L,which is placed in grooves formed by attaching cleats to the sides ofthe shoe B. The screen L, it' desired, may be made in two parts withtheir adjacent ends overlapping one the other, so that the middlin gsmay pass from one to the other of the said parts.

The part of the middlings which passes through the upper part of thescreen L falls upon the inclined board or chute M, and slides down itinto the discharge-spout N.

The partof the middlin gs that passes through the lower part of thescreen L, falls upon the inclined chute or board O, and slides down itinto the discharge-spout P.

The part of the middlin gs that cannot pass through the screen. L fallsfrom its lower end into the discharge-spout Q.

By this construction the different grades of the middlin gs are all keptseparate.

To the forward end of the frame A is attached a fan-blower, It, thedischarge-spout of which terminates beneath the upper part of the upperscreen, H.

To the opposite sides of the shoe B are attached the ends ofcross-boards Sto guide a portion of the blast against the upper. part ofthe screen H. The guide-boards S, one or more of which may be used, maybe adjustable or stationary.

The direction of the blast may be further eontrolled,if desired, bymaking the bottom of the blast discharge-spout adjustable, or byarranging an adjust-able board upon the said bottom.

To one end of the fan-shaft is attached a v-small pulley, T, to receivethe band by which it is driven, and which also passes around a largerpulley, U, attached to the end of the shaft V. The shaft V revolves inbearings in the lower rear part of the frame A, and to its other end isattached a crank, NV, or pulley with which the driving power isconnected.

To the middle part of the shaft V is attached a cam-wheel,X,wl1ichoperates against a lower rear part of the shoe B, or against a block orplate attached to it, to move the said shoe B and its attachmentsforward.

The shoe B is thrown back as soon as released from each cam of thecam-wheel X by a spring, Y, attached to the forward end of the frame A,and the tension of which is regulated as required by two set-screws, Z,passing in through a bar of the frame A.

To the shaft V, or to the large pulley U, is attached a small pulley,A', to receive a band, which also passes around a large pulley, B',

attached to the end of the shaft C.

rlhe shaft G' revolves in bearings attached to the middle parts of thetop side bars of the frame A, and to its middle part are attached twocams, D', which, as the said shaft C' is revolved, raise the hammerE',and allow them to drop upon 'cross-:bars h2, attached to the screen H,to jar the said screen, and prevent the screen-cloth from becomingclogged.

The hammers E ame hinged at their alternate ends to cross-bars of theframe A.

To the free rear end of one of the hammers E' is attached the upper endof a strap, F', which passes down through the space between the rear endof the shoe B and the rear ends of the upper screen,H, and the upperchute, I.

The lower end of the strap F' isattached to the free rear end of thehammer G', placed above the lower screen,L, and the forward end ofwhich'is hinged to the forward part of the upper chute, I, so that thehammer G' may be operated to strike a cross-bar, Z', of the screen L andjar the said screen by the movements of the upper hammer E'.

The rearward movement of the shoe B is limited by a stop-bar, H',secured to the rear end of the frame A by screws I', so that the said,movement of the said shoe B may be regulated by adjusting the saidscrews l'.

Having thus described my invention, I claim as new and desire to secureby Lettersy Patent- 1. The combination, in a middlings-separator, of theclosed chest B I, the inclined bolt, the knockers, the blast fan, andthe blast boards, the latter arranged beneath the head or feed end ofthe bolt, as shown and described.

2. The combination of the closed chest, the inclined bolt having thefinest cloth at the feed end, the knockers, the blast-fan, and theblast-boards arranged beneath the iine cloth at the feed end, for thepurpose specified.

3. The combination of the hammer E', strap F', hammer G', and screen L,as and for the purpose specified.
